Letters Patent No. 93,660, dated August 10, 1869.

IMPROVED RAILWAY-CAR SEAT.

The Schedule referred to in these Letters Patent and making part of thesame,

To all whom it may concern Be it known that I, T..G. THEAKER, ofBridgeport, in the county of Belmont, and State of Ohio, have invented anew and useful Improvement in Railroad- Car Seats and Oouches; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference bein g had to the accompanying drawings,in which- I Figure 1 is a side elevation;

Figure 2 is a front elevation;

Figure 3, a vertical section, taken in the line a x of and Figures 4, 5,6, 7, and 8, are views of some of the parts in detail.

Like letters designate like parts in all the figures.

The nature of my intention consists in the peculiar ,-arrangements ofdevices for oscillating the seat of a railroad-car chair, and also Iorchanging the position 'of its back, by which meansfthe various changescan be made with facility, without the occupants being compelled to risefrom their seats. v

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the drawdng- A Arepresent the side pieces of the frame to which theseat-frame B, of the chair, is pivoted at or near their upper ends, bymeans of a rod, a, which passes through the pieces A A, and also throughthe seatframe B.

The side pieces A A have feet or flanges at their lower ends, by meansof which they are bolted to the floor of the car, and are also seemed ata proper .distance apart by means of a rod, b, which passes through themat a convenient distance below the rod a, said rod having a nut on eachend outside the side pieces.

There is also a brace, G, which extends iiom near the top of the sidepiece A to near the. bottom of the side piece A, its ends being boltedthereto.

In the piece A is a slot, (1, which is an arc of a circle, the radius ofwhich is the distance from it to the rod a.

Extending down from, and seclired to the cross-tie B, of the frame ofthe seat of the chair, is a V-shaped hanger, O, on one side of which isthe boss or projection L, which forms a bearing for the shaft O, whichshaft extends through the slot (1, some distance outside the piece A;

On the inside of this side piece A is a cogged segment, 1).

On the shaft 0 is a pinion, I), which engages with the cogsegment D.

Secured to the outer end of this shaft is a box, E, having two arms, ee, which form the lower bearings for the vertical or inclined shaft 13,its upper bearing being on the inside of one side of one of the outerpieces ofthe frame of the chair-seat.

Secured to this shaft is a worm or screw-pinion, F, which is placedbetween the arms e e, of the box E.

This engages with a'pinion, E, in the box E, said pinion being keyed tothe shaft 0',

.On the upper end of the shaft F is a crank-knob or hand-wheel, f, bymeans of which the shaft is revolved. The arms'of the chair areconstructed in the same manner as those described in my patent, datedApril 27, 1869. In the grooves of the arms are placed the slides g ofthe same construction as those used in my patent hereinbefore mentioned.

On the outside of these slides are sliding pieces, h,

in which are slots, 1', through which the wrist a, on

the side of the slide g, projects.-

The ends of the sliding pieces It are inclined or bev. elled, to enablethem to pass under the arms j, and between them and the slides g; theobject of this being to hold up the front pawls above the projections orstops in the bottom of the grooves in the arms, so

that when it is desired to raise the back, the slides will move forwardwithout hindrance from the front pawls. At the same time the pawls nextto the back hang loosely, so as to fall into the recesses between theprojections, and take hold of said projections in order to hold the backin any desired position.

.011 the outside face of the sliding pieces h are projections, j, therebeing one near each end.

To the wrists n, on the slides g, are attached the bars 16, one end ofwhich is attached to the wrist of theslides g, and the other to the backof the chair.

The front ends of these bars project a short distance beyond the wristsof the slides g, and against the inside of the front projections therebykeeping the front ends of the sliding pieces it forward, their endsbeing under the arms of the front pawls, thus holding them up above theprojections in the arms.

During the operation of reversing the back, the bars 10 are mined, andtheir front ends, (which'arc semicircular,) strike the projections j onthe other ends of the sliding pieces h, thereby moving their other endsunder the arms of the rear pawls, (which now become the front ones,) andraise them, at the same time allowing the others to fall into therecesses in the bottom of the grooves in the arms.

To oscillate the seat, turn the shaft F, by means of the hand wheel j,which turns the worm or screwpinion F, which engages in the pinion E,thereby causing the shaft 0 to revolve, and with it the pinion D, whichengages with the cog-segment 1), thereby causing the pinion D to movebackward or forward on the stationary segment D, carrying with it the-frame, rod I), and brace c,

and hanger, or supporting-frame, 0, all substantially as and for thepurposes set forth and described.

and for the purposes shown and de- The combination of the shaft F, screwor wormpinion F, wheel E, pinion D, and segment D, all substantially asand for the purposes set forth.

4. The regulating slide pieces 7:, substantially as set forth, incombination with the slide 9, alent, substantially as and for thepurposes set forth.

5. The combination of the arms 7:, slides h and 9, all substantially asshown and described.

6. The combination of the knob or crank f, shaft- F,'screw-pinion F,pinion E, pinion D, and cog-segment D, all substantially as set forth,and for the purpose of oscillating the chair-scat.
